Hi PN,
Yes! We can absolutely walk you through it. Please call our Support Team at 1-800-732-8238, and we would be happy to send you a new tub spout with a diverter under warranty. The tub spout can be easily replaced. This tub spout has 2 different installation methods, either with the adapter and set screw underneath, or it’s threaded. The instructions to do so are also in your installation manual on page 4, step 5B. If you don’t have the installation manual, we provided a direct link below. In either case, if you need our help, we are here for you. As the original purchaser of the product, you are backed by our Pforever warranty, which protects your faucet's finish and function for as long as you own it. We look forward to assisting you.
